High-speed centrifugal extractor control solution for textile dyeing industry

Using INVT’s new generation multi-function inverter GD200A to control the high-speed centrifugal extractor helps the system operate smoothly, avoid shaking, shorten the drying process, save time and improve production efficiency.

Centrifugal extractor is an important equipment in many different production stages in industrial fields such as yarn, fabric, textile and dyeing, medical, food, etc. used to separate water by spinning, creating a large centrifugal force meets operator’s requirements. The old-style control method, the centrifugal extractor is started in star, delta and mechanical brake is used to stop the motor.

CUSTOMERS’ DIFFICULTIES

The large starting current causes a voltage drop on the plant power line.
Instant start causes mechanical shock, sinificantly affecting belts, pulleys, bearings, etc.
Using mechanical brakes is very easy to wear and tear, frequent maintenance and replacement.

SOLUTION ANALYSIS

DAT offers a solution to control the high-speed centrifugal extractor by installing the INVT GD200A universal inverter for the extractor motor. The system uses a DBU dynamic brake (built into the inverter below 37 kW) combined with a discharge resistor to brake the motor.
